TIEVisionOCR.getRegions

Declaration

function getRegions(textOnly: bool32 = false): TIEVisionVectorRect; overload; safecall;
function getRegions(image: TIEVisionImage; textOnly: bool32 = false): TIEVisionVectorRect; overload; safecall;

Description

Detect text regions (layout).
First overload takes last processed image as input.
Second overload takes the specified image as input.

Parameter	Description
image	Source image
textOnly	If true then only text regions are returned. If False image regions (with no text) may also be returned

Note:
◼A shortcut method for this is available: OCR_GetRegions
◼getRegions should be used with the ievOCRAuto_OnlySegmenting or ievOCRAuto segmentation modes
◼You can draw the rects to canvas using DrawRects

Example

OCR.setSegmentationMode(ievOCRAuto);
regions := OCR.getRegions(image);
for i := 0 to regions.size()-1 do
  with regions.getRect(i) do
  begin
    str := m_OCR.recognize(image, IEVisionRect(x, y, width, height));
    // Do something with str
  end;
